Cigarette case outer package image acquisition equipment and system

Abstract

The invention relates to cigarette outer package detection, in particular to cigarette case outer package image acquisition equipment and system. The cigarette case outer package image acquisition equipment (1) comprises: a housing (2) having an upper-layer illumination chamber and a lower-layer illumination chamber, the upper-layer illumination chamber and the lower-layer illumination chamber being internally provided with light emitting sources for illuminating an outer package of a cigarette case (20); a partition plate (8) arranged between the upper-layer illumination chamber and the lower-layer illumination chamber, a transparent area (11) being arranged on the partition plate (8), and used for supporting the cigarette case (20) and exposing the lower side face of the cigarette case (20) to the lower-layer illumination chamber; a vertical shooting module comprising an upper camera and a lower camera, the upper camera and the lower camera being located in the upper-layer illumination chamber and the lower-layer illumination chamber respectively and used for shooting the upper side face and the lower side face of the cigarette case (20) respectively; and a horizontal shooting module comprising four cameras, arranged in the upper-layer illumination chamber and used for shooting the vertical surfaces of the periphery of the cigarette case (20). According to the scheme, cigarette case outer package image acquisition can be carried out with high quality.

Description

technical field [0001] The invention relates to detection of cigarette outer packaging, in particular to an image acquisition device and acquisition system for cigarette outer packaging. Background technique [0002] The image collection of cigarette packs is an important source of data for identifying the authenticity of cigarettes. In the analysis of authentic cigarette pack images, high-quality and standardized cigarette pack images are required. [0003] At present, there is no special equipment on the market for quickly collecting images of the outer packaging of cigarette packs. Usually, when cigarette retail stores, industrial and commercial departments, and inspection departments need to collect images of the outer packaging of cigarette boxes, they usually take pictures manually through mobile phones, digital cameras and other equipment. The cigarette pack images collected by the current method usually have the following problems: 1) The operation is cumbersome, an...

Problems solved by technology

The cigarette pack images collected by the current method usually have the following problems: 1) The operation is cumbersome, and the cigarette pack needs to be turned over manually; 2) The image is greatly affected by the ambient light, and there are often reflections and color distortions; 3) The image is focused Inaccurate, detail information is lost; 4) The scale of the image is different, and the size of the cigarette box in the images taken by different photographers and at different times is too large; 5) The plane points of the cigarette box are not on the same horizontal plane, and the projective distortion is serious
